Powershell |无法找出陷阱功能

Question

好的我不知所措＆gt;。＆gt;我尝试过try / catch和trap函数，它不会发现这个错误......

# Adjustable Variables
$Computers_Path = ".\Compuers.txt"
$Log_Path = ".\Log.txt"

# Script Specific Variables


# Validate Adjustable Variables
TRAP { Write-Host "Unable to locate list of computer names at $Computers_Path"; Continue; }
$Computers = Get-Content $Computers_Path

Answer 1

试试这个：

$Computers = Get-Content $Computers_Path -ea stop

这使得trap能够捕获异常。
